Supported workflow
What this YAML online editor supports
Common config-style YAML is parsed locally and shown as a JSON-style result. It is designed for focused snippets and learning tasks where a fast browser workspace is more useful than a full local project.
- Validate simple key-value configuration data
- Parse strings, numbers, booleans, null values, and basic lists
- Preview the parsed structure as readable JSON
- Keep configuration drafts in local browser storage
Runtime, files, and honest limits
- Browser runtime
- Lightweight local YAML parser
- File types
- .yaml, .yml
- Privacy
- Your source stays in the browser workspace during normal use; ToolerWork does not need a code-execution backend for this runner.
- Limit: Anchors, aliases, tags, multiline scalars, and deeply nested advanced YAML are outside this lightweight parser.
- Limit: Use a full YAML implementation before shipping a complex production configuration.
